LIQUID-DISPENSING MACHINE.

Specification of Letters Patent.

Patented June 13, 1,916.

To all whomz't may concern:

Be it known that 1, WILLIAM Gr. Hon- LiNGswonTH, an Ainerican-born citizenxof the United States, residing at Sheboygan, in the county of Sheboygan and State of Wvisconsin, have invented new and useful Improvements-V in Liquid-Dispensing Machines, of which the following is a specification.

The invention relates to dispensing machiiies, and has for an object to provide .a

machine for dispensing liquids, particularly fluid soap and the like, and embodies various ifnprovenients over'a patent granted to me on a liquid v.dispensing machine, January 23, i912, No. 1,015,680.

The invention resides, more particularly, in a machine which ispreferably used in wash roomsand suitably mounted over the usual basin to take the place of the ordinary cake of soap, and whereby, when the hand is held beneath the machine and pressure is applied toa knob forming a part of the Inachine, a quantity of the liquid soap is received in the palm of the hand, thus not only providing ya sanitary structure but presenting a device in which a quantity of fluid soap is delivered which is sufficient to permit of properly washing the hands so that there will be no waste of the soap in the use of the same, as is usually the case when a cake of soap is employed in public wash rooms and the like.

In the further disclosure of the invention reference is to be had to the accompanying drawings, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in which:

Figure 1 is a vertical sectional view of the device, showing the plunger ln initial position; Fig. 2 is a similar view showing the plunger in final position to discharge Huid soap from the casing; Fig. 3 is a verticalA transverse sectional view taken through the plunger on the line 33 in Fig. 1; Fig. 4 is a. horizontal sectional view taken on the line `Referring more particularly to the views, I provide a bracket 10 adapted for attachment to a wallto support a casing 11 including an integral circular supporting iange 12, adapted to threadedly receive and support a vessel 13, preferably made of glass and adapted to contain fluid soap.

It will be seen by referring to Figs. 1 and 2 that the vessel `13 is normally in an inverted position .so that the fluid soap will gravitate. into the casing 11. Now in order to permit of filling the vessel 13 with a fluid soap, the casing 11 is mounted to turn on the bracket 10, and this is accomplished. through the medium of a shank 14 extended from one end of the casing andhaving slid-. able connection with the bracket 10, thesaid shank being provided with a head 15, with an expansible spring 16 encircling the shank and abutting against the head 15, and a circular flange 17 of the bracket 10, thus normally retaining they casing in abutting positionagainst the bracket. A plurality of oppositely arranged apertures 18 are provided in the flange 17, and locking lugs 19 projectfrom the shank 14, the said locking lugs being adapted to fit into the apertures 18 to rigidly lock the casing in an' upright position on the bracket, it being readily understood that when the casing is in this position the vessel 13 will be in an inverted p0- sition as shown in Figs. 1 and 2 and that by simply pulling outwardly on the casing against the. action of the spring 16 the locking lugs 18 will be moved out of the aper tures 18 and the casing including the vessel 13 can then be rotated on the bracket until the casing is in upright position so that the same can be readily unscrewed from the' ange 12 for the purpose of filling the vessel.

The casing 11 is provided with an inlet 20 having communication with the vessel 13 and an outlet 21 leading to the exterior of the casing, andniounted to slide longitudinally within the casing is a plunger 22, a. suitable closure 23 being arranged lori-one end of the casing to prevent the plunger from bcing withdrawn exteriorly thereof, with a stein 24 projecting from anend of the plunger and passing through an opening in the closure, the free end of the said stein having a knob 25 which, when pressed, 'will move the plunger longitudinally in the casing 11. The plunger is provided with a longitudinal groove 26 into which projects a screw 27 supported on the casing 11, thus preventing rotation of the plunger withv respect to the' casing and aiding substantially in guiding the plunger in its longitudinal movement in the casing, the inner end of the said plun.- ger being engaged by an expansible spring Q8 abutting against an end of thecasing 11 andhwhich normally retains the plunger 22 in initial position. The longitudinal movement of the plunger within the casing to normal position under the influence of the spring ,may be retarded by adjusting the screw 27 which movementA regulates the quantity of fluid passing from the passage 30l through thel passage 29 to the outlet 21 in tlie casing 11.

lThe plunger 2'2 is provided withwa longitiidinal passage 29 and similarly, the casing 11 is provided'ivitha .passage 30, the passage 29, however, being out of register with the passage 30 when the plunger. 22 is in normal position. "Now it will be apparent that the fluid in the vessel 13 will gravitate into the casing '11. and fill up the space around the spring 28 so that when the plungeiis pressed against thev action of the spring the inlet will'be closed bythe plunger, as it ladvances in the casing, while at4 Athe same time thepas'sage 29 will be moved into registrationwith the passage and will. also remain in communication with the ofutlct 21 so that the advancement of the plunger 22 in the casing 11 will press the the casing until the '.'vessel 13 is movedinto g #luid in the casing through the passage 30 finto the passage 29 and thence outwardly lthrough the outlet 21 in the lowerendfof the casing 11. rlhe momeiit the pressure is released from the` plunger the spring 28 will ,return the plunger to normal position, thus eutting ofithe exit of fluid from'the casing, fis will be. readily seen, this being accompllished' by a lateral projection'81 of the' casing 11 and which separates the '30;fom the passage 29.

Passage s mentioned heretofore, when it is' desired`to 'fill thewessel 13 with a fluid, it is simfily necessary to pull outwardly on the casin bracket 1-O aiidl then impart a ,half turn'to an upright yposition 'so that the samecan be conveniently unscrewed from the casing and filled with the desired fluid, after which the rotation of the'casing isrreversed until the vessel is in the position shown iii Figs. 1

11 `-to unlock the same from theA Witnesses "plunger and through which the fluid is forced from the casing through the outlet can be arranged to'either extend through the .plunger or formed on the surface 4or peripliery thereof. I, therefore, do not limit myself to the particular construction disclosed, the scope of the invention being lefined in the appended claim.

Having thus described my claim: In a device of the class described, in c oniinvention, I

.bination, a substantially tubular bracket,

said bracket being formed with a substan- `tially fiat wall, said wall Ibeing formed transversely with a substantially rectangular slot, a substantially tubular casing having a fiat wall adapted to contactsaid fiat wall of the bracket, a shank integrally formed concentrially upon said/easing, a

rectangular locking lug formed at the base l of said shank and adapted to be received in `said slot, a head upon the -free end of said shank, a spring bearin at 'one end against said head and at the ot er end against said first named wall whereby to hold saidflat wallslin engagement, a liquid dispensing" vessel having its mouth discharging into' said casing, saidwcasing having a delivery. poi-t', a valve reciprocating in said casing, a

spring in said easing'v compres'sible by said valve'when it moves in the direction of said first named spring, I means wherebfy said valve may uncover said port, and a push rod' 90' carried -b said valve. i

VIn testimony whereof I afiix my signature in presence of two witnesses. I
